,WINDOWQOPERATING'DE iCn-v" 1 To all whomit mag concern." I

Be it known that I, CLARENonVIo'roR JONES, a citizen of the Unit'ed States of America, and resident of 230 You e street, city of Toronto, county of York, rovince of Ontario, in the 'Dominion of Canada,

have invented certain new and useful Improvements in- Window-Operating Devices, of which the following is a specification;

The invention relates to improvements n window operating devices as described n the present specification and illustrated in the accompanying drawings that form a part of the same. 3 j i The invention consists essentially of the novel means employed for securing a wlndow in any desired position against the pressure of springs adapted to open same.

The objects of the invention are to provide a means whereby casement windows opening to the outside may be ad usted without the necessity of the operator reaching out of the window, to avoid displacement of screens and the like when adjusting the window, to prevent damage caused by windows being blown open or shut and generally to provide a window operatlng device which will be inexpensive to manufacture, simple of operation, durable and efiicient.

In the drawings Figure 1 is a view of a window locked in an open position.

Fig. 2 is a cross sectional view on the line A--A of Fig. 1.

Fig. 3 is a detail view of a form'of catch adapted to hold the operating chain to any desired position, one side of said catch being broken away to disclose the interior construction. I

Fig. 4 illustrates a modified form of chain catch.

Like numeralsof reference indicate corresponding parts in the various figures.

Referring to' the drawings the window 1 is provided with two-or more reverse hinges 2 adapted to exert an outward pressure on said window to open same, each of said hinges consisting of a pair of plates 3 from which extend inwardly from the top and bottom thereof lugs 4 adapted to accommodate a pintle 5, a coiled spring 6 encircling said pintle between the lugs 4 and having its ends 7 projecting on to said plates to force same apart, and a pair of plates 8' Specification of Letters Patent the window and frame.

the hinge to In'mounting a'window in its frame the plates3 of the hinges are forced together against the pressure of the spring 6 and one of the plates '8 is secured on the inner frame 11 of the window and the other of said plates is secured to the inner sid'e of the window sash so that said sprin will (lonstantly exert pressure to open sai winow. I

The outward movement of the window caused by the pressure of the spring hinges is controlled by means of achain 12 secured to the windowsashin any desired location andoperating through acatch mounted on finger 16 pivotally mounted on a transverse pin 17 adjacent to the upper end of said portion 14 and having a shoulder 18 intermediate of its length projecting downwardly and forming with said wall 15 jaws adapted to grip said chain and hold the window from further outward movement.

The finger 16 preferably projects considerably beyond the portion 14 and has its outer end 19 increased somewhat in width thus forming a greater surface for engagement by the chain.

In the employment of the catch described above it is preferable to use a form of chain in which the links have narrow looped portions 20 terminating in widened flat ends 21, as shown in the drawings, so that the jaws will grip the flat portion in advance of the looped portion and thus effectually prevent the outward movement of the chain.

It will have been seen from the foregoing that to open the window it is only necessary to grasp the loosely hanging portion of the chain and by raising it upwardly lift the end of the finger 16 sufficiently to admit of the looped portion of said chain passing between the gripping jaws when the spring hinge will force the window open. When the window has opened sufficiently the operator simply has to drop the chain and the finger'immediately drops down and the chain is gripped as before. To close the catch but it is preferable to reverse the ends j thereof so that the narrowloopedjaortion windowitis only-necessary to pull inwardly on the chain the required vdistance and then dropsamer In Fig. 4 a modified form'of catch is shown in which the chain operates through I automatically opening window sash mounta box like structure 22 having-its end adj acent to the window opening and its front end provided with a narrowslot23 into which the reduced portionof a link is adapted to drop to {prevent further outward 'movement. The same form of chainis' used with this catch. as with, the first described of a link will drop I intosaid slot and the widened flat portion will abut the side walls of said slot. Y

e To adjust the window it is only necessary to raise the chain from the slot 23 and althe window is covered by a screen it is only necessary to slot the frame of the screen to accommodate the form of catch employed and the window may then' be adjusted without interfering with said screen.

What I claim is j The combination of a window frame, an

ed therein, a chain connected to'th'e'sash for r I closing; it, a bracketsecured to the window frame and having. a bar projecting outwardly therefrom to support the chain, a' clamping lever pivoted transversely above the chain in said bracket and having an intermediate ratchet tooth automatically engagingthe links of the chain above said bar; the free endof the lever extending longitudinally above the outer portion of the chain and adapted to be raised and released thereby when the outer portion of the chain israised.
